What Is the Correct Site for an Infant Heel Puncture?

Infant heel puncture, also known as a heel stick or newborn screening, is a common procedure performed on newborn babies to collect blood samples for various tests. These tests are crucial in identifying potential health conditions that can be treated early on. However, it is essential to ensure that the heel puncture is performed correctly to minimize discomfort and maximize accuracy. In this article, we will discuss the correct site for an infant heel puncture and address some frequently asked questions regarding the procedure.

Correct Site for an Infant Heel Puncture:

The heel puncture is typically performed on the lateral or outer aspect of the infant’s heel. This area is chosen because it provides easy access to the capillary bed, which is necessary for obtaining an adequate blood sample. The lateral aspect also has a lower risk of damaging any underlying structures, such as tendons or bones.

To locate the correct site for the heel puncture, healthcare professionals often use landmarks such as the medial and lateral malleoli. The medial malleolus is the bony prominence on the inner aspect of the ankle, while the lateral malleolus is the bony prominence on the outer aspect. The puncture site is usually about 1 cm below the imaginary line connecting these two landmarks.

It is crucial to clean and disinfect the puncture site before the procedure. Healthcare professionals often use an alcohol wipe or antiseptic solution to ensure that the area is sterile. After cleaning, they will perform the puncture using a sterile lancet or a similar device. Once an adequate blood sample is obtained, it is collected on a special filter paper or into a tube for further analysis.
